Who Should Build Your Next Product?

Commercial drilling is a critical undertaking for many industrial projects. It is a necessity for those in businesses such as mining and geothermal power generation. They have to dig deep to explore the treasures lying deep in the earth's layers. Furthermore, commercial drilling comes in handy for socio-economic projects like large-scale water provision. The water derived from such wells is supplied to cities for residential and commercial use. Indeed, succeeding in such projects requires a thorough understanding of the technical aspects of commercial drilling. Here is the information you need to know when venturing into such a project: 

The Drilling Equipment

The outcome of a commercial drilling project starts with having the right tools for the job. There are two popular drilling rigs you can use in this case: the cable tool and rotary rigs. The cable tool is also referred to as the percussion rig. 

Cable tool rigs

A cable tool is not a traditional drill because it doesn't rely on power to rotate the drilling bit. The method here uses a heavy bit that rises and drops repeatedly to crush the underlying soil formation. Some of the basic components of a cable tool include a drill line, drill bit, spring, spudder and a pitman arm. The pitman and spudder arms perform the up-and-down motions that enable the driller to break large crevices, caverns and nearly any formation. 

Rotary drills 

The use of rotary drills is the most common method of commercial drilling. A typical rotary drill features a tall mast, carrier, water injection system, hydraulic devices and rotary tables. The rotary table applies torque to rotate drill pipe and drilling collar. Simultaneously, the drilling fluid circulates through the drill pipe and other openings, cleaning the cuttings generated by the drill bit. 

The Benefits of Cable Tool Rigs 

Cable tool rigs have distinctive benefits when it comes to drilling. First, the method does not create any plugging, which often causes mud formations when drilling. Moreover, rigs are cost-effective and relatively easy to maintain. One or two drillers are enough to carry out the job. They are also easy to set up and transport to and from the site. 

The Benefits of Rotary Drills 

Rotary drills also have some outstanding features. The most notable one is the option for reverse circulation where the drilling fluid moves through a part called the annulus. Your drillers can regulate the speed of this fluid and keep the equipment from eroding the walls when drilling. This means that rotary drills do a neater and more environmentally friendly job.
